Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solid material packaging equipment, in particular to a solid sodium cyanide packaging vibration device. BACKGROUND

[0002] Solid sodium cyanide is a basic chemical raw material commonly used in the industrial fields of metallurgy, chemical industry, electroplating, etc. Its finished product form is mostly granular or block solid, which has the characteristics of strong hygroscopicity, fine dust, and certain toxicity. In the industrial production process of solid sodium cyanide, after the raw materials are treated by reaction, cooling and solidification, drying and crushing, etc., they need to be filled into bags, barrels or other containers by packaging equipment for storage, transportation and sales.

[0003] Due to the uneven particle size distribution of solid sodium cyanide in the drying and crushing process, the material often contains different particle sizes such as large particles, fine powder and medium particles. If not screened directly, it is easy to cause uneven packing density, settlement or stratification during transportation, and also affects the dissolution rate and reaction control accuracy when used by customers.

[0004] In the prior art, some enterprises use simple vibration platforms or single screens to pretreat the pre-packaged solid sodium cyanide material, but such devices have single structure, poor classification effect on granular material and low screening efficiency, and usually only have a single discharge port, which is difficult to realize split output.

DETAILED DESCRIPTION

[0029] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0030] Please refer to Figures 1-5 The embodiment of the present application provides a kind of solid sodium cyanide packing vibration device, including support frame 100, vibration cavity 200, vibration component 300, elastic support component 400 and upper cover 500.

[0031] Support frame 100 is located in the lower part of the vibration device, for carrying vibration cavity 200 and providing support;Elastic support component 400 is arranged between vibration cavity 200 and support frame 100, and vibration cavity 200 is installed above support frame 100 by elastic support component 400;The top of vibration cavity 200 is connected with upper cover 500, and optionally, the periphery of vibration cavity 200 is uniformly provided with a plurality of locking buckles for connecting upper cover 500.After opening upper cover 500, it is convenient to clean and maintain the inside of the device.Vibration cavity 200 is provided with sieve plate 600 and can cooperate with the vibration of vibration component 300 to vibrate and convey the incoming material and realize the screening of material, and vibration cavity 200 is provided with first discharge port 201 and second discharge port 202 for raw material grading output and independent discharge on the discharge side, wherein first discharge port 201 is used for discharging larger particle materials that do not pass through sieve plate 600, and second discharge port 202 corresponds to the discharge path of fine particle materials passing through sieve hole after screening, and optionally, first discharge port 201 and second discharge port 202 are both vertically downward, and the discharge does not interfere with each other.Vibration component 300 includes two vibration motors 310 arranged symmetrically at the lower part of vibration cavity 200 and inclined, for vibrating the material in vibration cavity 200 by composite vibration;Upper cover 500 top end face is provided with exhaust pipe interface 510 for guiding volatile gas in vibration cavity 200 to discharge on the discharge side deviated from vibration cavity 200, and external gas treatment equipment is connected through exhaust pipe interface 510.

[0032] The vibration device for packaging solid sodium cyanide provided by the embodiment forms a bearing mode with flexible transition in structure through the elastic support assembly 400 arranged between the vibration cavity 200 and the support frame 100. Compared with direct rigid connection, the connection mode established through the elastic support assembly 400 can share part of the impact force when the vibration motor 310 operates, thereby reducing the structural severe load fluctuation caused by vibration, and also enabling the vibration cavity 200 to produce moderate shaking, so as to facilitate the dispersion and screening of the material.

[0033] In the above embodiment, the vibration assembly 300 is provided with two vibration motors 310, which are respectively fixed to the left and right sides of the lower part of the vibration cavity 200 and are arranged in an overall inclined and symmetrical manner. Through this symmetrical and inclined layout, the vibration motors 310 can form a composite force in the horizontal direction and the vertical direction when operating synchronously, and the reasonable superposition of vibration force helps to make the particles fully dispersed on the screen surface for screening. Under this composite vibration driving, the material can continuously tumble and roll in contact with the screen holes during movement, thereby improving the contact opportunity of particles and screen holes and promoting the rapid passing of fine particle materials through the screen holes. Compared with the single vibration device mode, the composite vibration can effectively shorten the residence time of the material on the screen surface, reduce the risk of hole blockage caused by long-time accumulation, speed up the process of classification processing, and synchronize the screening action with the material transfer in use, which helps to improve the screening efficiency as a whole and is suitable for rapid classification operation of solid particles.

[0034] In addition, the upper cover 500 is arranged at the top position of the vibration cavity 200 in the embodiment of the application, which can isolate the material screening area from the external space. The upper end face of the upper cover 500 is provided with an exhaust pipe interface 510 at a position close to the discharge end, which is used to guide the released gas, especially when processing volatile or hygroscopic raw materials such as sodium cyanide. In the embodiment, the volatile gas hydrogen cyanide generated in the hygroscopic reaction of sodium cyanide. The exhaust pipe interface 510 is arranged as an exhaust passage, which helps to reduce the pressure change caused by the accumulation of gas in the vibration cavity 200, and also provides an interface for connecting the rear-end gas treatment equipment. Through such a structure, the cleanliness of the working space can be improved to a certain extent, the influence on personnel health and the surrounding environment is reduced, and the device operation process is closer to the actual requirements of industrial safety and environmental control.

[0035] In some embodiments, the screen plate 600 is a square metal plate uniformly distributed with screen holes. Specifically, the metal screen plate 610 can be a stainless steel punched plate, and the screen plate 600 can be detachably installed in the vibration cavity 200. After the upper cover 500 is opened, the installation, replacement and cleaning and maintenance of the screen plate can be conveniently performed. Alternatively, the screen plate 600 is installed in the vibration cavity 200 through a clamping groove structure. Further, the screen plate 600 is arranged in the vibration cavity 200 in a tilted manner with the feeding side being higher and the discharge side being lower.

[0036] In the embodiment, the sieve plate 600 adopts a square metal plate structure with a plurality of sieve holes uniformly distributed thereon. Such a structure has good rigidity in use and is not prone to deformation under the influence of vibration, which is conducive to maintaining the stability of the sieve holes. Moreover, the sieve plate 600 is arranged in a detachable manner inside the vibration cavity 200. Such a structure can bring high convenience in device operation and maintenance. When the sieve holes are worn, clogged, or need to be replaced with sieve plates of different aperture diameters, the sieve plate 600 can be directly taken out from the inside of the vibration cavity 200 for replacement, without the need to disassemble the vibration cavity 200 as a whole. The disassembly and assembly process is simple, which helps to reduce the downtime of the device required for maintenance, facilitates regular cleaning and maintenance, prolongs the service life of the sieve plate 600, and improves the adaptability of the device under different screening working conditions.

[0037] In addition, the sieve plate 600 is arranged in an inclined manner during installation, with the high end facing the feeding direction and the low end close to the discharge side. In combination with the composite vibration provided by the vibration motor 310, the sieve plate 600 arranged in this inclined manner can make the material gradually slide downward under the combined action of the vibration force and the self-weight, avoiding the material jumping in place or oscillating back and forth on the surface of the sieve plate 600. In this way, on the one hand, it helps to form a flow state of the material on the surface of the sieve plate 600, improving the continuity of screening; on the other hand, it also facilitates the rapid discharge of the screened particles, reducing the possibility of accumulation and retention, making the discharge process more smooth, and thus improving the screening efficiency of the material.

[0038] In some embodiments, the inside of the vibration cavity 200 is a hollow cavity and is divided into a first material cavity 210 above the partition plate and a second material cavity 220 independent of the first material cavity 210 and below the partition plate by the sieve plate 600. A first material guiding channel 204 in communication with the first material cavity 210 is arranged between the side wall of the vibration cavity 200 at the discharge side and the sieve plate 600. The first discharge port 201 is in communication with the first material guiding channel 204 and can be used to discharge the coarse particle material screened above the sieve plate 600. The inclination direction and angle of the bottom plate of the vibration cavity 200 are consistent with those of the sieve plate 600. A second material guiding channel 205 adjacent to the inner side of the first material guiding channel 204 is arranged on the bottom plate of the vibration cavity 200. The second material guiding channel 205 is in communication with the second material cavity 220. The second discharge port 202 is in communication with the second material guiding channel 205 and can be used to discharge the fine particle material below the sieve plate 600.

[0039] In this embodiment, the screen plate 600 is arranged inside the vibration cavity 200 and divides the space inside the vibration cavity 200 into two relatively independent areas, namely the first material cavity 210 above the screen plate 600 and the second material cavity 220 below the screen plate 600. Through this separation method, the coarse and fine particle materials are naturally guided into different material cavities after screening, forming physical isolation in space. This structure not only reduces the possibility of particle mixing, but also helps to maintain the classification state of the particles during discharging, making the final discharged material particle size distribution clearer and avoiding the interference of different particle size materials in the subsequent process.

[0040] On the discharging side of the vibration cavity 200, the first material guiding channel 204 is arranged between the screen plate 600 and the side wall of the vibration cavity 200, which is used to guide the coarse particle material in the first material cavity 210 to the first discharge port 201 and smoothly discharge. The arrangement path of this material guiding channel is short, so that the large particles can slide out of the vibration cavity 200 quickly under the action of natural gravity and vibration force, reducing the accumulation and material back plugging phenomenon caused by retention. During continuous operation, this structure also helps to reduce the local wear of the cavity bottom caused by particle erosion, improving the smoothness of the whole machine operation.

[0041] Consistent with the screen plate 600, the bottom plate of the vibration cavity 200 is also designed to be inclined, and the direction and angle are consistent with the screen plate 600, and the second material guiding channel 205 is opened on the bottom plate of the vibration cavity 200. The fine particle material after screening can fall into the second material cavity 220 and slide down along the inclined bottom plate of the vibration cavity 200, enter the second discharge port 202 through the second material guiding channel 205. This guiding method helps to form a continuous flow of material, reduces the risk of blockage caused by too long residence time, and also improves the discharge efficiency of fine particle material, making the discharge more uniform and smooth, suitable for stable operation in high frequency and continuous operation scenarios.

[0042] In some embodiments, the support frame 100 is a four-column frame structure with four columns, and the support frame 100 is composed of rectangular steel pipes welded together. The bottom of the column of the support frame 100 is provided with a plurality of through holes for fixing the anchor bolts, and the column of the support frame 100 is fixedly connected with the ground through the anchor bolts to ensure the stability of the device during operation.

[0043] This embodiment adopts a four-column support structure, and the support frame 100 has four columns, which has good overall space stability. The four columns are connected in sequence to form a symmetrical and balanced frame system. During the operation of the device, especially when the double vibration motors 310 work alternately or cooperatively, the support frame 100 can better share the load, thereby reducing the risk of deformation.

[0044] Meanwhile, the support frame 100 of the embodiment uses rectangular steel pipes as basic components, and the overall splicing can be completed by welding. The cross-sectional structure of the rectangular steel pipes has good compression and bending resistance. The welding connection ensures the structural strength, makes the node more compact, and has stronger overall rigidity, is not easy to produce connection loosening, and is also convenient for factory batch production and installation application.

[0045] In addition, multiple through holes are arranged at the bottom of the four support columns of the support frame 100, which facilitates fixing the device to the concrete ground or platform foundation through anchor bolts. This fixing method has strong adaptability in common industrial sites, which is beneficial to reduce the overall displacement or deviation of the device caused by vibration during operation. Moreover, the through-hole type connection point is also convenient for subsequent maintenance, maintenance or adjustment of the device position, and can realize repeated disassembly of the device without damaging the integrity of the support frame 100, thereby enhancing the flexibility and convenience of on-site use.

[0046] In some embodiments, the elastic support assembly 400 includes four compression springs arranged below the side of the vibration cavity 200 and arranged vertically, each compression spring is fixedly connected with the top of the four support columns of the support frame 100, the front and rear sides of the vibration cavity 200 are respectively provided with left and right symmetrically arranged connection blocks 203, the top ends of the four compression springs are respectively fixedly connected with the bottom ends of the connection blocks 203, and the top of the four support columns of the support frame 100 and the bottom of each connection block 203 are respectively provided with a connection column for connecting the compression spring.

[0047] In the embodiment, the elastic support assembly 400 is composed of four compression springs, which are symmetrically distributed on the vibration cavity 200. The compression springs are installed in a vertical manner to form a four-point elastic support structure, which can disperse the load fluctuation generated during the operation of the vibration cavity 200 in multiple directions, thereby reducing the violent shaking or deviation caused by uneven local stress and keeping the device in a stable posture during continuous operation.

[0048] In addition, the lower end of each compression spring is fixed to the connection column arranged at the top of the support column of the support frame 100, and the upper end of the compression spring is connected to the connection block 203 arranged on the vibration cavity 200 in the same way. The connection column structure is used at the upper and lower ends, which on the one hand simplifies the installation process and improves the connection consistency of each support point, and on the other hand reduces the possibility of uneven stress on the spring caused by installation errors.

[0049] Further, the connecting block 203 of the present embodiment is symmetrically arranged on the front and rear sides of the vibration cavity 200, and has a certain reinforcing function. While bearing the function of connecting the compression spring, the connecting block 203 also serves as a local force-bearing component to enhance the fatigue resistance of the structure of the vibration cavity 200, thereby reducing the risk of damage to the vibration cavity 200 caused by long-term vibration.

[0050] In some embodiments, the outer end of the exhaust pipe interface 510 is provided with an external flange (not shown in the figure). In the present embodiment, the outer end of the exhaust pipe interface 510 is provided with an external flange, which, although it is a partial structural improvement, can bring more stable connection effect in actual application. The flange 511, as a standard interface element, can be used to connect the exhaust pipe interface 510 with external gas treatment equipment. During installation, the operator can connect the external flange with the interface flange of the downstream equipment pipeline through bolts, and the connection process is stable and reliable, which is conducive to reducing the risk of gas leakage.

[0051] Solid sodium cyanide is easy to release volatile gas (hydrocyanic acid gas HCN) during the vibration screening process. Since hydrocyanic acid gas is a highly toxic gas, if not promptly discharged, it can adversely affect the working environment of the operating personnel. Therefore, the stable mounting mode provided by the external flange enables the exhaust pipe interface 510 to be more reliably connected to the gas treatment equipment, avoiding the problem of gas leakage caused by loose connection.

[0052] In addition, as a standardized connecting component, the external flange has good universality in size, tolerance and mounting method. This standard connection form also provides convenience for subsequent maintenance or system modification of the device, facilitates disassembly, replacement or upgrading of related external facilities, and improves the compatibility and maintenance efficiency of the device in various use environments.

[0053] In some embodiments, the top end face of the upper cover 500 is provided with a feed inlet on the side opposite to the exhaust pipe interface 510, and a feed hopper 230 is arranged at the feed inlet. The feed hopper 230 has an inverted frustoconical structure, and is fixedly connected with the feed inlet of the upper cover 500.

[0054] In the present embodiment, the feed hopper 230 adopts an inverted frustoconical structure, which is wide at the top and narrow at the bottom in geometric shape. The material can slide downward under the action of gravity, which is conducive to realizing continuous flow. The frustoconical shape concentrates the center of gravity of the material, which facilitates the material to naturally fall into the feed inlet arranged below without the need for additional auxiliary devices. Moreover, such involvement helps to maintain the continuity of material flow and reduce the probability of blockage caused by stagnation.

[0055] On the top end surface of the upper cover 500, the feed inlet is arranged at a position close to the feed side, and the exhaust pipe interface 510 is located at the opposite end. This structural layout makes the feed path and the exhaust path independent of each other, and can better maintain the orderliness of the airflow inside the vibration cavity.

[0056] In some embodiments, a sealing gasket is arranged around the top of the vibration cavity 200 between the vibration cavity 200 and the upper cover 500, to ensure the sealing of the connection to prevent dust and volatile gas leakage.

[0057] In this embodiment, a sealing gasket is arranged around the top of the vibration cavity 200 between the vibration cavity 200 and the upper cover 500, and is installed at the contact position of the two. This continuous ring-shaped sealing structure can form a closed state on the entire contact boundary, which helps to reduce dust leakage or gas overflow caused by small gaps.

[0058] Moreover, the sealing gasket also has a certain deformation buffering capacity as a flexible connecting member. Under the driving of the vibration motor 310, the vibration cavity 200 will produce mechanical vibration during operation. By arranging the sealing gasket, a certain elastic transition can be formed at the joint surface, which helps to reduce the transmission of vibration impact and reduce the local wear rate.

[0059] In addition, the use of the sealing gasket also makes the later maintenance more convenient. When the upper cover 500 needs to be disassembled for internal inspection or replacement of the screen plate 600, the operator does not need to use adhesive or other sealing materials for repeated treatment of the sealing part, but only needs to replace a new gasket or reinstall the original one to restore the sealing state. This design reduces the complexity of maintenance operations, shortens the maintenance cycle, and reduces the problem of secondary leakage caused by poor sealing, thereby improving the overall user experience from the aspects of device operation convenience and operation stability.

[0060] In some embodiments, the vibration assembly 300 further comprises a motor connecting shell 320 and two mounting plates 330. The motor connecting shell 320 is fixedly installed at the bottom end of the vibration cavity 200, and the motor connecting shell 320 is a reverse trapezoidal plate frame structure. The left and right sides of the motor connecting shell 320 are respectively connected with the mounting plates 330, and the two vibration motors 310 are fixedly connected to the motor connecting shell 320 through the mounting plates 330.

[0061] In this embodiment, the motor connecting shell 320 adopts an inverted trapezoidal plate frame structure. Its geometry of wide top and narrow bottom facilitates increasing the acting area on the bottom of the vibration cavity 200 and can more stably realize the connection with the bottom of the vibration cavity 200. During the vibration process, the vibration motor 310 will periodically generate strong vibration force. The inverted trapezoidal structure is fixed with the vibration cavity 200 through the wide top, which is conducive to dispersing the impact force on the bottom of the vibration cavity 200 and reducing the possibility of fatigue or deformation of the local structure due to stress concentration. Compared with directly installing the vibration motor on the bottom of the vibration cavity 200, the vibration cavity 200 structure can be better protected.

[0062] At the same time, the motor connecting shell 320 of this embodiment is arranged in the central area of the bottom of the vibration cavity 200 and adopts a central installation mode. This layout can make the vibration force more balanced when transmitted to the vibration cavity 200. Moreover, the symmetrical linkage between the vibration motor 310 and the motor connecting shell 320 helps to maintain the vibration of the whole device to be stable. In addition, the mounting plates 330 are arranged on both sides of the motor connecting shell 320, and the vibration motor 310 is connected and fixed with the motor connecting shell 320 through the mounting plates 330. This left-right symmetrical arrangement not only facilitates the installation and positioning of the vibration motor 310, but also provides a convenient condition for subsequent adjustment and replacement of the vibration motor 310.

[0063] In some embodiments, the first discharge port 201 and the second discharge port 202 are both arranged in an open vertical downward manner.

[0064] In this embodiment, the first discharge port 201 and the second discharge port 202 are both arranged in a vertical downward opening manner. This arrangement conforms to the natural material falling path after screening and can reduce the accumulation of materials at the discharge port, facilitating the rapid discharge of materials from the vibration cavity 200 under the action of gravity.

[0065] Especially for materials such as sodium cyanide, electrostatic adsorption is easily generated due to mutual friction during screening. In the discharge structure design, the downward discharge manner can effectively shorten the residence time of particles in the discharge area, so that the coarse particle materials and fine particle materials separated by the screen plate 600 can respectively leave the vibration cavity 200 along the corresponding first material guide channel 204 and second material guide channel 205, and finally be discharged from the first discharge port 201 and the second discharge port 202, respectively, which helps to reduce the re-mixing between different particle sizes and improve the clarity of classification.

[0066] In addition, the discharge port structure is relatively simple, facilitating docking with downstream equipment such as a collecting hopper, a conveying device or a packaging unit, and has strong adaptability in terms of modular integration of the device. Through reasonable design of the structure, not only is it beneficial to improve the material discharge efficiency, but also makes the entire discharge process more stable and smooth, suitable for continuous production conditions, and has a positive effect on the actual operation efficiency of the entire machine and the process connection effect.

[0067] After understanding the structural composition of the device and the connection relationship between its components, in order to facilitate further understanding of the practical application mode of the present application by those skilled in the art, the use process of the solid sodium cyanide packaging vibration device will be briefly described as follows in combination with the above structure:

[0068] Before using the present embodiment, the entire machine should be placed on a solid and level ground, and fixed using foundation bolts through the through holes at the bottom of the support frame 100 to enhance the stability of the device during operation. After installation, check the connection state of the four compression springs arranged between the vibration cavity 200 and the support frame 100, and confirm that they are in good stress state. At the same time, it is also necessary to check whether the connection between the power supply line and the vibration motor 310 is normal, and after the preparation work is completed, the running process can be entered.

[0069] In the feeding stage, the operator uniformly feeds the pretreated solid sodium cyanide particles into the feeding hopper 230. The feeding hopper 230 is a reversed conical frustum structure, and the material will naturally slide down under the action of gravity, be introduced into the vibration cavity 200 through the feeding port arranged at the top end of the upper cover 500, and finally fall into the first material cavity 210. In order to avoid the accumulation of gas during the vibration process affecting the working environment, the exhaust pipe interface 510 should be connected to the gas discharge device in advance, which helps to improve the safety and air circulation quality of the working area.

[0070] After the device is started, the two inclined and symmetrical vibration motors 310 start to operate synchronously, and the generated composite vibration force is transmitted to the vibration cavity 200 through the motor connecting shell 320 and the mounting plate 330. The material slides from the feeding side to the discharging side under the vibration of the sieve plate 600, and receives continuous sieving action during the movement. The sieve hole size forms a separation for different particle sizes, and the large particle material is retained above the sieve plate 600 to continue to move forward, and the fine particle material falls into the second material cavity 220 to continue to move forward, forming a grading process.

[0071] After sorting, the coarse particle material will enter the first discharge port 201 along the first guide channel 204, and the fine particle material will be guided out by the second guide channel 205 from the second cavity 220 and discharged from the vibration cavity 200 by the second discharge port 202. Both discharge ports are vertically downward opening structures, which helps the material to quickly separate, reduces the possibility of retention, blockage and cross mixing. The separated materials enter the subsequent collection container or packaging system according to the particle level, adapting to different process requirements.

[0072] After use, turn off the power, and after the equipment stops vibrating completely, the operator can disassemble the upper cover 500 to clean or replace the screen plate 600. If aging, wear and other phenomena are found in the sealing gasket, it can also be replaced. The whole device has compact structure layout, is convenient to disassemble and assemble on site, and has simple and efficient maintenance process, and is suitable for the application requirements of screening and discharging sodium cyanide particles in continuous production scene.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
